Blend modes

Blend modes (or Mixing modes) in digital image editing are used to determine how two layers are blended into each other. The default blend mode in most applications is simply to hide the lower layer with whatever is present in the top layer. However, as each pixel has a numerical representation, a large number of ways to blend two layers is possible.
Note that the top layer is not necessarily called a "layer" in the application. It may be applied with a painting or editing tool.

Normal blend mode

This is the standard blend mode which uses the top layer alone, without mixing its colors with the layer beneath it.

Where a is the value of a color channel in the underlying layer, and b is that of the corresponding channel of the upper layer. The result is most typically merged into the bottom layer using "simple" (b over a) alpha compositing, but other Porter-Duff operations are possible. The compositing step results in the top layer's shape, as defined by its alpha channel, appearing over the bottom layer.

Screen (ice hockey)

In ice hockey, a screen is obstruction by a player of the goaltender's view of the puck. The word can also be used as a verb, commonly "don't screen the goaltender", or "the goalie was screened". Screens can be both planned, as when an attacking forward positions himself in front of the net, or accidental, like when a defensemen accidentally blocks the goalie's view. Attacking players may attempt to take advantage of a screen by taking a shot, which the opposing goalie cannot attempt to save if he is being screened.

Super!

Super! is an Italiantelevision channel owned by De Agostini. The channel was launched on September 1, 2010 as DeA Super on Sky Italia. After 2 years, it changed name to Super! on March 18, 2012. The network official speaker is voice actor Renato Novara.

Programming

Super! shows a variety of programs targeted towards children and teenagers. There are a number of original series, as well as acquired programming from Nickelodeon in the United States, including Sam & Cat, Zoey 101, Fanboy and Chum Chum, and more. Some acquired series on Super! are not Nickelodeon's, like SciGirls.

Super! was the first Italian television channel airing a Korean drama, Dream High, from September 1 to October 16, 2013, the only Korean television series broadcast in Italy. However, the series was heavily edited, and dubbed into Italian, names were changed to English alternatives (for example, Hye-mi became Sam, Sam-dong Brian, and Jin-guk Dylan), episodes split in two parts, some scenes cut to reduce the duration of the episodes or to censor the content unsuitable for young audiences, mainly blood. And finally a new Digimon series called Digimon Adventure tri.

Plot

Short-order cook Frank Darbo (Rainn Wilson) says in voice-over that he has only two good memories from a disappointing life: marrying his beautiful wife, Sarah (Liv Tyler), and an incident in which he directed a police officer to catch a purse snatcher. Frank immortalizes these two events in a pair of crayon drawings that he hangs on his wall for inspiration.

Later, Sarah, a recovering addict, leaves Frank for Jacques (Kevin Bacon), a charismatic strip club owner who gets her hooked on drugs. Frank sinks into depression, where he has a vision in which he is touched by the finger of God and meets the Holy Avenger (Nathan Fillion), a superhero from a public-access television show on the All-Jesus Network, who tells Frank that God has chosen him for a very special purpose. Frank believes that God has chosen him to become a superhero and goes to a local comic book store for inspiration. His claim that he is designing a new superhero is met with enthusiastic appreciation from the foul-mouthed store clerk, Libby (Ellen Page). Frank creates a superhero costume and assumes the identity of "The Crimson Bolt."

Inheritance (object-oriented programming)

Inheritance (OOP) is when an object or class is based on another object (prototypal inheritance) or class (class-based inheritance), using the same implementation (inheriting from an object or class) specifying implementation to maintain the same behavior (realizing an interface; inheriting behavior). It is a mechanism for code reuse and to allow independent extensions of the original software via public classes and interfaces. The relationships of objects or classes through inheritance give rise to a hierarchy. Inheritance was invented in 1967 for Simula.

Inheritance should not be confused with subtyping. In some languages inheritance and subtyping agree, whereas in others they differ; in general subtyping establishes an is-a relationship, whereas inheritance only reuses implementation and establishes a syntactic relationship, not necessarily a semantic relationship (inheritance does not ensure behavioral subtyping). To distinguish these concepts, subtyping is also known as interface inheritance, whereas inheritance as defined here is known as implementation inheritance or code inheritance. Still, inheritance is a commonly used mechanism for establishing subtype relationships.
